It applies no matter what Finder you use. I've seen Roulette parties try to speed run Wanderers and fail miserably because the tank never speed ran before/healer doesn't have the output to keep the tank alive/DDs aren't geared enough to kill mobs fast enough... Who speed runs Duty Finder? Clearly some people think anyone can make a speed run out of any dungeon and not fail miserably in the process. If there's room for abuse, then people are going to abuse it. It's not a matter of if, it's a matter of when. And sadly, how often.
